Well, you can never say never, but I've never seen any.
I suggest fabricating your own by edge gluing flat plastic or wood strips at the angle you want.? You can even file or sand an edge to have an angle for a better fitting joint.
For wood, if you have one of those little hobby table says, you could cut strips with an angle on one edge for gluing.? (22.5 degree edges will make 45 degrees when joined.)

Is 45 degree angle stock available, either in wood or plastic?
